Er, no offence, but how is this news?
Not entirely sure on this but I don't think documentation was available then.
Lol. It's news to me, I didn't know it was released until yesterday :)
V4 is fantastic so far. Looking forward to the final release.
What's new in v4?
First framework to use flexbox for the grid? Or did someone else do that already?
Foundation offered an optional flexbox grid with the launch of version 6.
And Bootstrap's is optional too.
